yea thats why I said get it or go home, this is one of the few mods that is WELL WORTH the MONEY! One member one here bought the AA Exhaust and was regretting it b/c of the drone from 1.5k-2.5k range. I also had a buddy of mine with a fully modded IS350 say (at a cold start) the BMW PE sounds like their is a v8 under the hood. I laughed but he said he was serious, but all I know is that the BMW PE is the best exhaust for this car.
